New commissioner..... Waiver day and commissioner access questions

Wondering if a league can permit 2 or 3 people access to make roster changes, etc. ??????
Also, we want weekly waiver pickups only. If we select "Tuesday", will that make Tuesday the day stats start to accumulate? We also want Tuesday to be stat day for roster moves. Can someone comment?

1) Each team can have one co-manager. This co-manager would have access to make roster changes, trades, etc.
2) If you are using Continuous Waivers then, yes, you can set waivers to only process on Tuesdays. However, keep in mind that in H2H leagues the matchup week is Monday thru Sunday and that cannot be changed or customized.

It is also possible to have a "co-commissioner" as well that can be given full power. However, this "co-commissioner" must be one of the other managers and a member of the league - it cannot be some third party person not affiliated an any way with the league.
